C++ :: If Statements - Display Randomly Selected Number For 20

Jun 4, 2014

IF statement. Really new, so this will be simple I'm sure. I'm essentially just trying to roll a 6 and 20 sided die. I want the statement to run "If 20,then display the randomly selected number for 20".

// auto dice roller
#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
using namespace std;

const char* twenty[20] = {
"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"

C# :: Display Listview Items In Actual System Fonts

Sep 11, 2014

I'm trying to use a listview component to show all the fonts on my system, and display each item (row) in the actual font design.

When I run the following code, nothing displays in the listview.

If I rem out line 4, then the list populates with all the fonts, but of course, in the default listview font.

I thought I read somewhere that each item in a listview can be set to a different font.

int i = 0;
foreach (FontFamily oneFontFamily in FontFamily.Families) {
listView1.Items[i].Font = new Font(oneFontFamily, 10);
listView1.Items.Add(oneFontFamily.Name);
i++;
}

C :: Max / Min Value In Randomly Produced Array

May 10, 2014

I am very much a beginner at C and a large amount of it still tends to go over my head, I've created a 2d array which its size is generated from user input and filled with random integers. Next I need to locate the maximum and minimum figures in the integer and as dull..This is the code I have so far

Code:

#include <stdio.h>#include <stdlib.h>
int main ()
{
int firstDimension, secondDimension, firstDimensionIndex, secondDimensionIndex,index;
int **table;
}

C++ :: How To Iterate Through A For Loop Randomly

Apr 5, 2013

So I have a vector that I want to iterate through randomly, and by random I mean that each element is only accessed once but I don't want to shuffle the vector because the vector elements are large. So I want this functionality:

std::vector<SomeLargeObjectWithoutACopyConstructor> myvec;
// ...fill myvec
std::random_shuffle(myvec.begin(),myvec.end());
for (auto& value : myvec)
{
// do stuff
}

Only I don't want to do this because the object type has no copy constructor and is large, so I don't want to shuffle the vector, just the iteration path. Is there a simple and efficient way of iterating randomly through a vector while ensuring that each object is only accessed once?

int main() {
// Constants

C++ :: Randomly Remove Points From Array?

Feb 19, 2013

I was wondering if there was a way to set up a code with an array of variable dimensions that removed random points on that array i.e.

1111
1111
1111

then randomly remove a point:

1101
1111
1111

and then be able to repeat this process until all points are removed.

C# :: Randomly Select Strings From Array

Mar 27, 2014

I am trying to select 3 questions randomly from a string array and create another array with the randomly selected questions then display them in labels.

As you can see in the code I have used Array.Clear method to remove the selected question from the array to prevent duplicate questions being selected. For some reason this is not working! The "Randomly" selected question is ALWAYS the 5th element [4] of the randomQuestions array and this element is duplicated for each iteration of the loop.

public void shuffleQuestions() {
string questionselected;
string[] randomQuestions = {
"What is the speed limit from the time you pass an Accident sign until you have passed the crash site?",
"What must you do at a red traffic light?",
"What is the maximum possible speed limit on the open road?",

C++ :: How To Define New Color That Is Randomly Generated In Allegro

Feb 5, 2014

How do i define a new color that is randomly generated in allegro.

I have this code here in the header file.

Code:

//FILE : circledefs.h
//PURP : Define some constants for circle & background
#ifndef CIRCLEDEFS_H
#define CIRCLEDEFS_H
#define NUMCIRCLES 3
//The frames per second for the timer
#define FPS 60

[Code]...

And what i want to do here is learn how to create a random number gen. Now a few questions if you don't mind telling me is.

1 - can I create 3 random generators in this header file? Or do I have to do this in main.

2 - If I do have to do this in main can I still create this defined RANDOM as a color.

3 - I am sooooo new to this all i know is cin and cout code for C++, so will i need to know more about pointers to do this.

4 - for fun how hard would it be to make a game in allegro that uses music to define how the enemy moves and attacks. (yes that would be the final project.

C++ :: How To Get Rid Of Negative Number From Randomly Generated Numbers

Oct 21, 2013

I have a error with one of my programs. I'm supposed to get rid of negative numbers when there are numbers that are randomly generated. Here is the middle part of the code.

{
int vectorLength = 10;
vector<int> bothSigns(vectorLength);
cout << " Input vector: ";
for (int i = 0; i < vectorLength; i = i + 1)
{ bothSigns[i] = rand()%201 - 100;

[code] .....

The part where i'm supposed to start is after the /////'s. However, whenever I input a number for the random numbers(not put in part of code), i keep getting a segmentation error.

C++ :: How To Check Equivalent Of Randomly Generated Alphabets

Mar 23, 2014

//This code gives randomly generated alphabets and if equal will cout the alphabet which is equal

1 #include <iostream>
2 #include <cstdlib>
3 #include <ctime>
4 using namespace std;
5 int main()
6 {
7 int a;
8 char array[10];

[Code] .....

My question is how to check that randomly generated alphabets are equal e.g in 22 number line it should give output of equal alphabets if they are equal but it does not give equal alphabets what wrong in this code mention the wrong statement, how will i get right answer?

C++ :: Randomly Generating Probabilities - Function Stuck

Oct 29, 2014

I've written some code to randomly generate probabilities:

int Queue::car_per_hr() {
srand( time( NULL ));
int prob = rand() % + 101; // Probability in percentage from 0 to 100
int cars; //no of cars per hr

[Code] ....

So it checks through the range of possibilities: 0-20%, 21-40% etc. I then have this to implement it:

#include <iostream>
#include <ctime>
#include "queue.h"
using namespace std;
int main(){
Queue car_wash;
int NO_HOURS;

[Code] .....

For some reason though, everytime I call the car_per_hr() function, the probability just stays the same. It's output is always locked to the same thing it had to begin with?

C++ :: Function To Randomly Determines Suit And Value Of A Card

Jul 19, 2013

I'm writing a card game and I'm having trouble getting the first part of it right, which is picking out a random card from the deck and displaying it to screen. So it's supposed to display a different card every time i run the function in the program. The problem is, I keep getting the same output every time "Nine of Hearts".

This is what I have so far,

#include <iostream>
using namespace std;
//declare two string arrays
//one holds the "suit" of the cards, the other hold the "value"
string suit[] = {"Diamonds", "Hearts", "Spades", "Clubs"};
string faceValue[] = {"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ace", "King", "Queen", "Jack"};

[Code] ......

This is the output I keep getting every time I run the program:

Nine of Hearts

This "random selection" function I'm trying to do is meant to work as a means of shuffling the cards in the beginning of every round in the game and displaying only the top card from the deck.
